    *a Approx. 10 m (32.8 ft.)
    *b Approx. 14 m (45.9 ft.)
    WARNING:

    Radio frequency radiation exposure information:

    • This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
    • This equipment should be kept with minimum distance of 20 cm (7.87 in.) between the radiator (antenna) and your body at all times during adjustment.
    • This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter.
    NOTE:
    • Perform measurements on a level surface.
    • Make sure that no large metal objects are within a 10 m (32.8 ft.) x 14 m (45.9 ft.) area in front of the vehicle. If possible, the surrounding area should also be free of large metal objects.
    1. Before adjusting the radar beam axis, prepare the vehicle as follows.
      1. Remove all excess weight from the vehicle (luggage, heavy objects, etc.).
      2. Check the tire pressure and adjust it if necessary.
      3. Measure the vehicle height.

        Refer to PROCEDURE - Step 2

      4. Remove the radiator support opening cover.

        Refer to PROCEDURE - Step 1

    2. Check and adjust the vertical direction of the millimeter wave radar sensor assembly.

      *a Level
      1. Remove dust, oil and foreign matter from the radar sensor level rack.
      2. Set a level on the radar sensor level rack.
      3. Check that the level's air bubble is within the red frame.

        *a Level
        *b Air Bubble
        *c Bolt
        *d Vehicle Front
        *e Vehicle Left
        *f 0°
        *g Red Frame

        OK

        Level's air bubble is within red frame.

        If the bubble is not within the red frame, use a screwdriver to adjust the bolt until the air bubble is within the red frame.

        HINT: 

        • The adjustable range within the level's red frame is +/- 0.2°.
        • The target angle is +0.2° (upward angle of 0.2°).

          Result

          Adjustment Direction Adjustment Procedure Adjustment Angle
          Upward Turn screwdriver to positive (+) side When screwdriver is turned once, adjustment changes by about 0.12°
          Downward Turn screwdriver to negative (-) side
    3. Adjust the reflector height.

      *1 Millimeter Wave Radar Sensor Assembly
      *a SST(Reflector)
      1. Adjust the reflector so that the center of SST (reflector) is the same height as the millimeter wave radar sensor assembly.
        • SST: 09870-60000 
          1. 09870-60010
        • SST: 09870-60040 

        HINT: 

        Prepare a 10 m (32.8 ft.) string, a string with a sharp-pointed weight (plumb bob) and a 5 m (16.4 ft.) tape measure.

    4. Place the reflector.
      1. From the center of the front bumper (center of the emblem), hang a weight with a pointed tip, and mark point B on the ground.

        *a String *b Weight
        *c Center point *d Point B
      2. From the center of the rear bumper (center of the emblem), hang a weight with a pointed tip, and mark point A on the ground.

        *a String *b Weight
        *c Center point *d Point A
      3. Using a piece of string that uses point A as a starting point and that passes through point B, make a straight line on the ground ahead of the vehicle 5 m (16.4 ft.) or more from point B.

        HINT: 

        • Make sure to secure the string (using tape, etc.) when it is taut.
        • Lightly flick the string with your fingers several times to confirm that the string is aligned with point B.
      4. Using a tape measure, measure a position 11 mm (0.433 in.) to the left of the 5000 mm (16.4 ft.) from the millimeter wave radar sensor. Place the reflector at that position.
        NOTE:

        Perform the operation as accurately as possible.

    5. Check the radar beam axis.
      1. When using the Techstream:
        1. Connect the Techstream to the DLC3.
        2. Turn the engine switch on (IG).

        9. Follow the Techstream display and continue with the adjustment.
          NOTE:
          • Confirm that optical axis distance is approximately 5 m (16.4 ft.).
          • If "Error beam axis" is displayed on the screen, press the "Yes" button, and repeat again.
          • Check that there are no metal objects in the specified area in front of the vehicle (refer to the NOTICE at the beginning of this adjustment procedure).
